Molecular Genetics, Royal Melbourne Hospital RCV002221384 SCV002498606 uncertain significance Frontotemporal dementia 2021-08-10 criteria provided, single submitter clinical testing This sequence change in MAPT is an intronic variant located in intron 5. This variant is present in a single individual in the European (non-Finnish) population in gnomAD v2.1 (1/194,904 alleles). To our knowledge, this variant has not been reported in the literature in any individuals with frontotemporal dementia. The results from multiple in silico splicing predictors (SpliceAI, MaxEntScan, NNSplice) indicate that this variant may impact splicing by disrupting the donor splice site of intron 5. However, the relevance of this prediction is unknown as exon 5 (also known as exon 6) is not present in any of the alternatively spliced MAPT transcripts expressed in the brain (PMID: 19263483). Based on the classification scheme RMH Modified ACMG Guidelines v1.4.0, this variant is classified as a VARIANT OF UNCERTAIN SIGNIFICANCE. Following criteria are met: PM2_Supporting, PP3.
